Abstract

The utility model discloses a hole grinding device, which is characterized by comprising a positioning disc fixed on a grinding machine spindle, a positioning sleeve fixed on the positioning disc, a positioning shaft in clearance fit with the positioning sleeve, and a floating compression mechanism consisting of a press plate and a spherical mat; during operation, the positioning shaft penetrate through a workpiece for loading the workpiece on the positioning sleeve, the floating compression mechanism is used for compression, meanwhile, the spherical mat is enabled to freely slide, the floating compression mechanism and the positioning disc are connected, and finally the positioning shaft is pulled out for carrying out inner hole grinding processing. Screws cannot be tightly screwed up, otherwise, the spherical mat cannot slide freely. The positioning sleeve is in clearance fit with the inside diameter of the workpiece to be processed. The hole grinding device has the beneficial effects that the datum reference of the hole grinding device is identical with the datum references of the gear-shaping process and subsequent finish machining process of the part, errors caused by reference conversion are avoided, and the radial run-out of a gear ring relative to the inner hole is ensured.

Description

A kind of honing device
[technical field]
The utility model relates to mechanical manufacturing field, relates in particular to a kind of honing device.
[background technology]
Machining straight bevel gear by adopting in prior art, as shown in Figure 1, straight bevel gear circle radial run-out 0.08mm, m=5, z=20, its specific (special) requirements of a=20. is inaccurate grinding after the heat treatment of left side.By conventional method, final step locates inner hole grinding with tooth, and this need to process a complicated especially fixture, and makes quite trouble.
[summary of the invention]
The problem existing for prior art, the purpose of this utility model is to provide a kind of honing device simple in structure, easy to use.
The technical solution adopted in the utility model is: a kind of honing device, it is characterized in that: comprise the positioning disk that is fixed on grinding machine spindle, be fixed on positioning sleeve on positioning disk, with the locating shaft of positioning sleeve matched in clearance, and the floating hold-down mechanism being formed by pressing plate and ball ring; During work, with locating shaft, penetrate workpiece and install on positioning sleeve, then compress with floating hold-down mechanism, guarantee that ball ring can arbitrarily slide simultaneously, floating hold-down mechanism is connected with positioning disk, finally locating shaft is extracted out and ground endoporus processing again.
Further, described positioning sleeve is fixedly connected with positioning disk by screw.
Further, described floating hold-down mechanism is connected with positioning disk by bolts and nuts.
Further, described ball ring is fixedly connected with pressing plate by screw, and contact-making surface is smooth.
Further, described screw can not be tightened, to guarantee that ball ring can arbitrarily slide.
Further, described positioning sleeve and processing work internal diameter matched in clearance.
The beneficial effects of the utility model are: the positioning datum of described honing device and part are identical at the positioning datum of gear-shaping operation and later finishing step, all with the large footpath of internal spline and location, left side.So just avoid benchmark transformed error, can guarantee the radial run-out of the relative endoporus of gear ring.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the utility model will be further described.
Fig. 1 is processing work schematic diagram;
Fig. 2 is the utility model work schematic diagram;

[specific embodiment]
Referring to accompanying drawing, the utility model is a kind of honing device, it is characterized in that: comprise the positioning disk 1 that is fixed on grinding machine spindle, be fixed on positioning sleeve 3 on positioning disk 1, with the locating shaft 5 of positioning sleeve 3 matched in clearance, and the floating hold-down mechanism being formed by pressing plate 4 and ball ring 6; During work, with locating shaft 5, penetrate workpiece 10 and install on positioning sleeve 3, then compress with floating hold-down mechanism, guarantee that ball ring 6 can arbitrarily slide simultaneously, floating hold-down mechanism is connected with positioning disk 1, finally again locating shaft 5 is extracted out and ground endoporus processing.
Described positioning sleeve 3 is fixedly connected with positioning disk 1 by screw a2.
Described floating hold-down mechanism is connected with positioning disk 1 with nut 9 by bolt 8.
Described ball ring is fixedly connected with pressing plate 4 by screw b7, and contact-making surface is smooth.
Described screw b7 can not tighten, to guarantee that ball ring 6 can arbitrarily slide.
Described positioning sleeve 3 and processing work 10 internal diameter matched in clearance.
According to unifying datum principle, this workpiece 10 is all located with He Tu1 left side, the large footpath of internal spline in gear-shaping operation and later finishing step.Identical with the positioning datum of above-mentioned mill internal clamp, so just avoid benchmark transformed error, can guarantee the radial run-out of the relative endoporus of gear ring.
Strict temperature and the chilling temperature controlled, reduces heat treatment deformation amount, further guarantees tooth runout amount.
Gap between locating shaft 5 external splines and bevel gear internal splined large footpath should be determined according to heat treatment deformation test.
The preferred embodiment that this utility model has been described at this, comprises that inventor is for implementing known optimal mode of the present utility model.The change of preferred embodiment is apparent for those of ordinary skills after reading above-mentioned explanation.Inventor wishes the rationally such change of application of those of ordinary skill, and inventor thinks and at this, clearly states different application and also can realize the utility model.Therefore, the utility model comprises all modifications and the equivalents of the purport of quoting in the claim of enclosing, and this allows in applicable law.In addition, any combination of all possible change of above-mentioned key element is also comprised by the utility model, unless pointed out in addition or obvious contradiction in context at this.
